UNGUILING APPARATUS.

To all whom it may concern.

Be it known that I, EDWIN FARGO, a citizen of the United States, residing at Vi ilson, in the county of illegheny and State of Pennsylvania, have invented certain new and uscl'ul luipriwenicnts in Uncoilin A paratus, of which the following is a specitication.

My invention relates to improvements in apparatus for coiling or reeling metal, in the form of flat sheets or strips, and relates particularly to mechanism for uncoiling or unwinding a tight compact roll, for delivcry to the loose winding lnachine.

Ordinarily, sheet metal, or as it is known, flat metal is wound. in tightly compacted rolls or bundles which have to be first unrolled or unwound and then re-rolled by hand or otherwise, for the purpose of providing sui'licient looseness in the roll to adniit of exposure of all the surfaces and Suecessive pickling operation.

The present application 'fOl'IllS a division of my original application filed April 17, 1918, Serial No, 761737, in which I have shown and described the coiling apparatus, with which the uncoiling apparatus of the present application is combined, and with which it forms a cooperating part. The present invention is therefore illustrated as used in connection with the coiling appa ratus.

In the drawings, illustrating one preferred form of the invention, Figure 1 shows in side elevation a complete apparatus enibodying both the coiling and uncoiling mechanism. Fig. a vertical sectional longitudinal View through the uncoiling apparatus, indicated by the line H, H, of Fig. 3. Fig. 2-3 is a transverse sectional view on the line Ill, III, of Fig. l.

The metal, which is to be loosely coiled or wound for the purpose of exposing its surface to the pickling operation, is usually first wound or rolled in a compact bundle or coil which may be placed within a suitable holder 3 having removable side p01 tions 4:, a, hinged at 5, 5, and brought together .at the top and there held by any suitable latch device 6, from which the strip 7 or metal is drawn outwardly through slot 8 for introduction to my improved coiling machine. The coil 2, depending on its width, is wound upon a supporting drum or core 9 having additional sections 9 for Specification of Letters Eatent.

Patented June 9, 191-1.

Divided and this application filed November 1 increasing or reducing its width, and a supporting shaft ll), the ends of which rest in and may roll along supporting 'tl'EtCl'iWflYS 31. in the upper edge portion of easing A. slJpploliu-nlal adjustable intervening sup port 12 may also be provided, which at the some time a s to pace the cores 9 and 9 apart. The when open rest on supjhufllllg brackets 13, providing for ample clearance to the interior.

The coiling machine, shown at the left side of .l, substantially the same in construction and mode of operation as illustrated and described in my prior application above referred to. it comprises a casing ll. having a generally cylindrical interior oil the desired curvature and dimensions to receive and contain the metal strip "4" as it is int-induced, and to coil it inwardly into a loosely wound bundle, by the conlining; effect of the inner surfaces, against which 1c uncoiling or advancing end portion of 1e strip engages. The casing 114: is proided with an suljustuble inner wall section ,8, pivotally mounted at 20, and the strip 7 is fed into the interior by means oi feed rolls 29, 29, located at each side of an entrance slot, the strip being fed thereby ever u supporting roller from casing 3.

The construction and operation of the invention will be readily apparent from the tore-going do ion. The uncoiling apparatus facilitates the furnishing of metal to the ceiling machine, and provides for the various contingencies of operation in up purutus of this type.

The machine is comparatively simple in construction and o niration, strong and dur able and not liable to get out of order. It may be changed or varied in different details or modified to suit various conditions of use, and all such changes are to be considered as within the scope of the following claims.

lVhat I claim is:

l. A. holding housing for coiled fiat metal consisting of a main casing having at each side a hinged side and top portion adapted to close the interior, a supporting drum and shaft therefor reuuimbly uiiountcd in the casing, and an outlet opening.

2. A bidding housing for coiled fiat metal consisting of a main casing having hinged side and top portions, :1 supporting druin consisting of a plurality of sect'nons a shaft comprising in combination a main base and housing prosided with adjustable covering portions,

means for locking the top portions together, and a plurality of supporting drum sections pivotally mounted within the housing.

6. In an uncoiling apparatus for sheet metal strips, the combination of a housing having a semi-cylindrical interior, longitudinally divided upper portions therefor hinged to the sides of the housing and providing when closed an outlet slot for the strip, and removable supporting drum mechanism rotatably mounted within the housing between its lower and up er portions.

'7. In an uncoiling apparatus for sheet metal strips, the combination of a housing having a semi-cylindrical interior, longitudinally divided upper portions thereforhinged to the sides of the housing and providing when closed an outlet slot for the strip, removable supporting drum mechanism rotatably mounted within the housing between its lower and upper oortions and supporting brackets at each side of the housing for the hinged upper portions.

in testimony whereof I hereunto affix my signature in the presence of two witnesses.
